Digital Health Works Only When the Workflow Works

A digital tool can look transformative on a screen while creating almost no improvement in care. A reminder is useful only if someone can respond. A decision aid matters only if recommended tests, medicines or referrals exist. A screening image shared remotely helps only if feedback returns in time and the patient can act on it. Digital health is therefore less a category of technology than a redesign of who receives information, who acts and what happens next.

The maternal and perinatal mHealth review offers a warning: across 36 articles describing 15 tools in 11 African countries, feasibility and acceptability were often encouraging, yet only one tool had reached national scale and interoperability and sustainability planning were uncommon. DREAM-GLOBAL shows a workflow-aware design, with community workers measuring blood pressure, readings moving through mobile systems and users feeding back on the process. Cervical screening illustrates the same principle through remote supervision and quality assurance.

Before asking whether an algorithm is accurate, implementation research should ask where its output enters the workflow, who is accountable for the next action, whether resources exist and what happens during downtime. Digital transformation succeeds when it reduces friction in a functioning pathway - not when it adds another screen to a broken one.
